I’m a senior Microsoft and full-stack developer/consultant with extensive experience across C#/.NET, SharePoint, Power Platform, Azure, Umbraco and Kentico/Xperience. I combine hands-on development with technical consultancy, systems integration, automation and troubleshooting.
My core development background is C#, .NET/.NET Core and ASP.NET Core. I’ve built bespoke business applications from the ground up and taken over, supported and modernised existing systems. I work across the full development lifecycle, including requirements gathering, solution design, backend and frontend development, APIs, integrations, authentication, deployment and support.
For the European Space Agency, I developed a .NET Core project management application integrating SharePoint, Azure Data Factory and REST APIs. The system managed thousands of projects and was used by hundreds of ESA users.
I also developed an event operations platform using ASP.NET Core MVC, Blazor and SignalR. It was used at large events at Wembley Arena and Stadium MK involving more than 1,000 people, with barcode-based equipment checkout/check-in and real-time operational functionality.
I have more than 10 years of SharePoint experience, including SharePoint Online, SPFx, React, TypeScript, PnP/PnPJS, Microsoft Graph, Microsoft 365, permissions, lists, libraries, migrations and bespoke development. My SharePoint clients have included Unilever, LGC, Kinly, Ekco and NAACP.
I’ve worked with Power Platform since around 2020, particularly Power Apps and Power Automate. Recent engineering-sector work involved taking over and improving an existing SharePoint/Power Platform system used by field engineers. I developed and maintained Power Apps and flows covering job management, digital service reports, data synchronisation and mobile signature capture.
My Azure and integration experience includes Azure Data Factory, Entra ID, SSO, Microsoft Graph and REST APIs. Recent Ministry of Defence work through Serco included an Umbraco 16 application with Entra ID SSO integration.
I’m also an experienced Umbraco and Kentico/Xperience developer. Clients I’ve worked with include British Airways, Tesco, Barclays, De Beers, Agria Insurance, the Ford Foundation and the UK Ministry of Defence.
One of my particular strengths is taking over unfamiliar or problematic systems, understanding how they work and diagnosing issues across code, data, integrations and business processes. I’m comfortable working directly with clients, gathering requirements and taking ownership of a solution rather than simply working from development tickets.
My technical toolkit includes C#, .NET, ASP.NET Core, MVC, Blazor, SignalR, Azure, SharePoint Online, SPFx, React, TypeScript, PnP/PnPJS, Microsoft Graph, Power Apps, Power Automate, Entra ID, REST APIs, Umbraco, Kentico/Xperience, HTML, CSS and JavaScript.
